How to calculate the error incorporated in measuring a (coercivity) M-H loop using VSM and PPMS?

16 April 2019 0 5K Report

How to calculate the error incorporated in measuring a (coercivity) M-H loop using VSM and PPMS? Is it only the sensitivity of the instrument/noise floor or something else(if I take the mass to be accurately measured and the shape to be independent of the measurement)? More precisely I should say what will be the instrumental error and how to calculate it? Is there any such formula or the generalized one?
